Abstract
An apparatus for reproducing and processing picture information for forming a picture signal corresponding to a subcode obtained from a recording medium on which, in addition to a coded information signal, graphic codes including picture information occuyping N (N being a natural number equal to or greater than 2) channels and a recording medium code for specifying the recording medium are recorded, the graphic codes and the recording medium code being inserted as the subcode of the coded information signal. The apparatus is provided with a program memory, an instruction generating device for generating an instruction for designating a channel to be selected out of the N channels by a manual operation during playing of the recording medium, a designated channel data generating device for outputting, in response to a program-play command, a designated channel data indicating a channel designated by the instruction stored in the program memory so that the picture signal is generated from a graphic code occupying a channel of the N channels designated by the designated channel data.
